What are the Florida Energy Code requirements for installing an air handler in the attic?

Thursday, July 5, 2018

You may have seen a sticker like the one shown below on the front of an electric panel in a newer home. Posting of the warning sticker is one of four requirements by the Energy Code section of the Florida Building Code (FBC 403.3.6) for air handler installation in an attic. The notice has to be in all capital letters, minimum 16-point size, with the title and first paragraph in boldface. Leakage of condensation water when a drain line clogs is the problem that it addresses, along with alerting the homeowner to the presence of an automatic device that will activate when a condensation drain clog occurs.

The other three requirements for installation of an HVAC air hander in an attic by The Florida Energy Code are:

  • The service panel face of the air handler must be located within 6 feet of the attic access hatch.
  •  The access hatch opening must be big enough to get a replacement air handler into the attic.
  •  A device must be installed to alert the homeowner or shut down the unit when the condensation drain clogs. An automatic shut-off device is the usual choice.

These requirements are in addition to the Florida Building Code’s general requirements for installing appliances in attics at 1305.1.3, which you can read about at our blog post What are the building code requirements for installing an appliance (furnace, air handler, water heater) in the attic?
